Piechaser -- The source is 'credible' enough but the report is wrong. Here is the Airbus text, from our link:
December 9, 2013
The AAIB today issued a
Special Bulletin recounting factual details surrounding the accident in Glasgow that occurred on November 29, 2013.
According to initial evidence collected following the incident, the aircraft struck the roof of The Clutha Bar with “a high rate of descent and low/negligible forward speed” without rotation of the main rotor or the Fenestron tail rotor. As previously reported, all rotor blades remained attached upon impact.
The helicopter fuel tank system contained approximately 95 liters of fuel at impact.
Now, if you click on the link to the AAIB report you'll see that the AAIB SB said "Once removed from the building, approximately 95 litres of fuel were drained from the fuel tank system"
So Airbus have misreported the AAIB. I'm not trying to score points, people lost their lives here. But there is potentially a large difference between having drained approximately 95l and a statement that there was approximately 95l on board. Of course they could both be true....and one hopes that they are....but in this field of engineering one has to be absolutely pedantic.
